So, here is the first list I have made with CWE as the main detachment. Let me know what you think.

Troops

10x Kabalite WarriorSplinter Cannon, 9x Splinter Rifle

6x Reavers2x Blasters

RavagerNight Shields

Basic idea I thought here was that the warlock goes with the guardians, (if no good psychic, I will go with primaris one). Farseer will start with Reapers, and tries to support both them as well as reavers and kabalites, depending on what I get. Archon goes with the 3-man escort to assault the best enemy units. Rangers will try to infiltrate somewhere nice to camp, Illic with them to provide extra sniping. Guardians will stay somewhere back or midfield, and the ravager will support them.
